if statement - batch file to check existance of directory if not exists then use alternate directory for file copy -

i trying write batch file copies exe file network location local location. works depending on windows version (xp or win7) user has select correct .bat file due different local paths needed copy. (they going startup folder ran every time user starts machine). first time i've ever worked writing batch files , lost when looking @ syntax if statements. if figuring out great.

here have works xp:

    rem @echo off      echo starting movefiles      set exitrc=0     set exitmsg=exitrc initialized     echo %exitrc% -- %exitms      copy "\\networkdrive\install\individual\program\movefiles.exe" "c:\documents , settings\all users\start menu\programs\startup\"      echo copied files pc       set exitrc=%errorlevel%     if not %exitrc% == 0 goto :exit      set exitmsg=processing complete      :exit      echo step: %exitmsg%  rc: %exitrc%     echo finishing movefiles      pause      exit %exitrc% 

here have windows 7:

    @echo off      echo starting movefileswin7      set exitrc=0     set exitmsg=exitrc initialized     echo %exitrc% -- %exitms      copy "\\networkdrive\install\individual\program\movefiles.exe" "c:\programdata\microsoft\windows\start menu\programs\startup"      echo copied movefileswin7 pc - users / public startup folder     set exitrc=%errorlevel%     if not %exitrc% == 0 goto :exit      set exitmsg=processing complete      :exit      echo step: %exitmsg%  rc: %exitrc%     echo finishing movefileswin7       pause     exit %exitrc% 

i have 1 batch file cover both scenarios there no confusion user on batch file run.

you can utilise environment variable %allusersprofile%.

on winxp default c:\documents , settings\all users

on win7/2008 default c:\programdata

there table available here: http://ss64.com/nt/syntax-variables.html

i see copy different file. not sure why that. maybe detect using method here: https://stackoverflow.com/a/2788764/1553090 -- otherwise perhaps should take advantage of %programfiles% , %programfiles(x86)% variables.

just elaborate on how might choose use these variables... can test win7 startup folder existence, , if it's not there fallback xp (regardless of whether exists).

set startup_win7=%allusersprofile%\microsoft\windows\start menu\programs\startup set startup_winxp=%allusersprofile%\start menu\programs\startup  if exist "%startup_win7%" (     set startup=%startup_win7% ) else (     set startup=%startup_winxp% )
